A single missile interceptor can cost American taxpayers tens of millions of dollars, and once it is fired, it is gone. The Pentagon wants a weapon that never runs out of ammunition.
Lt. Gen. Heath A. Collins, the Air Force officer who directs the Missile Defense Agency, told a Senate panel on April 15, 2026, that his agency is pushing to mount high-energy lasers on unmanned aircraft capable of destroying incoming missiles with beams of concentrated light. The weapon would draw from an electrical power supply rather than a munitions stockpile, giving it what Collins called “a near-unlimited magazine” and a dramatically lower cost per shot.
“Directed-energy systems can thin out missile salvos,” Collins told the Senate Armed Services Subcommittee on Strategic Forces during a hearing on the fiscal year 2027 budget. The language was deliberate: “thin out” signals that the agency sees lasers working alongside traditional interceptors, not replacing them, picking off cheaper or slower targets so that expensive kill vehicles can be saved for the threats that matter most.
Why the Pentagon is betting on lasers now
The math behind the push is stark. A Ground-Based Interceptor, the kind designed to stop an intercontinental ballistic missile aimed at the U.S. homeland, costs roughly $75 million to $100 million per unit. Even a smaller SM-3 Block IIA, fired from Navy destroyers, runs about $36 million. Adversaries like China and North Korea have been expanding their missile arsenals faster than the United States can build interceptors to match, creating what defense planners call a “cost-exchange” problem: it is far cheaper to build an offensive missile than to field the interceptor meant to stop it.
A laser flips that equation. Once the hardware is airborne, each shot costs little more than the electricity and fuel needed to keep the drone flying. Fire one shot or one hundred, and the marginal expense barely changes. Collins framed the technology as a way to stretch limited missile defense resources during a large-scale conflict, where an adversary could launch salvos specifically designed to exhaust American interceptor inventories.
The House Armed Services Committee hearing record confirms that Collins discussed both directed-energy technology and unmanned platforms during the session, linking them into a single operational concept: drones carrying lasers that could loiter near threat zones and engage missiles during their most vulnerable boost or ascent phase, when the rocket is moving relatively slowly and its thin skin is under maximum thermal stress.
Why drones solve the distance problem
A laser’s effectiveness drops sharply over long distances. The beam spreads as it travels, and moisture, dust, and atmospheric turbulence scatter its energy. A ground-based or ship-based laser would need enormous power to burn through a missile hundreds of miles away. Placing the weapon on a drone that can fly closer to a launch site shortens the engagement range and keeps the beam tight enough to do damage.
Unmanned platforms add another advantage: endurance. A crewed fighter jet can stay airborne for hours at most before the pilot needs rest, food, and fuel. A large surveillance-class drone can loiter for a full day or longer. Pairing that persistence with a weapon that never runs dry creates a defensive layer that traditional interceptors cannot replicate, a sentry that watches and waits, ready to fire the moment a rocket clears the launcher.
Collins’ emphasis on integration suggests the Missile Defense Agency is not treating laser drones as stand-alone gadgets. His testimony described fitting them into existing sensor networks, command-and-control systems, and the layered defense architecture the United States already operates. That framing positions the concept as an addition to the current shield, not a replacement for it.
The Pentagon’s expensive history with airborne lasers
Skeptics have reason to be cautious. The Defense Department tried this before and failed expensively.
In the early 2000s, the Airborne Laser Test Bed program attempted to mount a massive chemical laser inside a modified Boeing 747. The aircraft was supposed to shoot down ballistic missiles from hundreds of miles away. Instead, the program burned through billions of dollars, produced only limited test results, and was eventually canceled. A 2011 Government Accountability Office report, GAO-11-372, documented serious cost overruns and schedule delays, flagging transparency and accountability gaps that allowed spending to spiral before Congress stepped in.
The current proposal differs in important ways. Today’s military laser programs rely on solid-state and fiber laser architectures, including techniques such as spectral beam combining that merge multiple fiber laser beams into a single powerful output. These systems have largely supplanted the bulky, toxic chemical lasers of the earlier era. They are smaller, lighter, and far more efficient. Unmanned platforms eliminate the weight and life-support demands of a human crew, freeing up payload capacity for the laser and its cooling systems. But the core engineering challenges have not vanished. High-energy lasers generate punishing amounts of heat, requiring robust thermal management that adds weight and complexity. Power generation and storage remain hurdles: a drone must carry or generate enough energy to fire repeatedly while still meeting flight endurance requirements.
No public test data from the MDA confirms that today’s laser technology can reliably destroy a ballistic or hypersonic missile from a drone-sized platform under real combat conditions. Collins’ careful language about “thinning out” attacks, rather than stopping them outright, hints that the agency may be setting realistic expectations rather than promising a silver bullet.
Where military laser technology stands in early 2026
Collins’ proposal does not emerge from a vacuum. The Defense Department has been funding a series of high-energy laser demonstrations across the services that provide context for the MDA’s ambitions. Lockheed Martin’s High Energy Laser Scaling Initiative, known as HELSI, has been working to push laser output to the 300-kilowatt class, a power level that defense officials have described as necessary for engaging faster and more durable targets such as cruise missiles. Separately, the Layered Laser Defense, or LLD, system has undergone live-fire testing against rockets and unmanned aircraft in recent years, demonstrating that directed-energy weapons can track and destroy targets in flight.
The Army’s Directed Energy Maneuver Short-Range Air Defense program and the Navy’s work on shipboard laser weapons have also advanced the underlying technology, producing field-tested hardware that, while not yet drone-mounted, validates key subsystems such as beam directors, tracking software, and thermal management. These programs collectively show that the U.S. military has moved well beyond laboratory experiments, though none has yet demonstrated the combination of power, weight, and endurance that a drone-based missile defense mission would demand.
That gap between demonstrated capability and the MDA’s stated goal is where the risk lives. Scaling a laser from a ground-based or ship-based installation, where weight and power are relatively unconstrained, to an unmanned aircraft that must stay aloft for extended periods is a different engineering problem entirely. The progress across existing programs suggests the building blocks are maturing, but assembling them into a flyable, fightable weapon system remains unproven in the public record.
What the public record does not yet show
Several critical details remain absent from the congressional testimony and hearing materials reviewed for this article. No specific drone airframe has been named as the carrier for these lasers. No prototype testing timeline appeared in the available documents. Budget line items for directed-energy programs within the FY2027 request have not been broken out publicly, making it difficult to gauge how aggressively the Pentagon intends to fund the leap from concept to fielded hardware.
No official MDA contract announcements tying a specific manufacturer to a drone-mounted missile defense laser have surfaced in the hearing materials, either. That leaves open questions about which defense contractors stand to benefit, how competitive the procurement process will be, and how responsibilities might be divided among airframe designers, laser builders, and systems integrators.
Policy and operational questions also loom. Stationing armed drones near potential launch areas could require overflight permissions or basing arrangements with allies, raising diplomatic and legal complications. Rules of engagement for firing lasers in airspace shared with civilian aircraft would need careful development. And if the systems prove effective, adversaries are unlikely to sit still. Hardened missile skins, faster rocket burn times, and tactics designed to overwhelm or deceive laser platforms are all plausible countermeasures.
What Collins’ testimony signals for the FY2027 budget fight
The strongest evidence here comes from Collins himself, speaking under oath to a congressional subcommittee. His written statement is a primary government document reflecting official MDA policy, not speculation or a leaked slide deck. When the director of the Missile Defense Agency tells Congress that directed energy is a priority and ties it to the next budget request, that language carries institutional weight. It signals where money, personnel, and political capital are headed.
What it does not signal is certainty. No peer-reviewed study or operational test report has been cited in the available materials to confirm that current laser power levels, beam quality, and thermal management are ready for the mission Collins described. The GAO’s findings from the Airborne Laser debacle remain a cautionary benchmark: ambition without accountability can consume billions and deliver little.
For now, the defensible reading is this: the Pentagon has placed laser-armed drones at the center of its next missile defense budget request, betting that directed energy can help close the widening gap between growing missile threats and finite interceptor stockpiles. The congressional record confirms the commitment. Proving the technology works at operational scale is the part that comes next, and the part that has tripped up the Pentagon before.
